Total is capped at 24 seats — push past it and the independents give way. Both sides court the independents one vote at a time.

How to use

Drag admin, opposition, and independent counts. The hemicycle redraws bloc by bloc and the green arc marks the 13-vote majority. The coalition outcome — admin can pass, opposition can block, or the chamber hangs — updates live as either side reaches across the aisle to the independents.

The 13-vote threshold

Simple majority for most Senate decisions: 13 of 24. For constitutional amendments: 16. For impeachment conviction: 16. For removing a Senate President: 13.

An admin with 10 firm loyalists needs 3 of the independents. Pork-barrel allocations, committee chairmanships, and project endorsements buy independents one at a time.

How blocs form

Most senators run as independents but vote in informal blocs. After elections, the Senate President is chosen by majority caucus — usually the admin-aligned bloc. That choice determines committee chairs, which determines what bills move.
